Yeah, you can use a triangulate2D with your point input. Then use an attribute expression sop with the triangulate2d into the first input and your original points into the second input. Then in the expression node put @opinput1_P
If you have not yet checked out Touchdesigner you should, based off of Houdini 5 and then split off, it can share a lot of data, bgeo, chops, chan etc, and can do what you want with ease.

I have not looked into this, but I would check out the Derivitive forum and get a rift setup from there. http://www.derivative.ca/Forum
In all honesty, I don't think you need a lens shader, but more of a stereo rig, and then proper composting to take those two images and conform them into the way occulus needs them. While I have not done this, I have seen it done quite a lot and it is pretty easy.
Unfortunately, I do not think that the standard alembic workflow works out of the box with motion blur...Imre Tuske has an alternate alembic rop that will get motion blur working in Maya as far as his otl purports. but I have not tested it yet. I believe that it involves baking the motion vector colors onto the geometry. I don't have a link handy but believe that the otl's are hosted on github...
Thomas...great simple file. Do you know how one could do what Maya calls a tri-planar projection, where the texture is projected along all six axis of a cube regardless of UV's?
Could you not just render a ramp using the object bounds on whatever axis you wanted that way getting a full range from 0-1 without having to worry about remapping to an objects specific. You could do it in a vop or simply uv project and texture with a ramp. I have rendered a lot of height maps for both terrain and parallax mapping this way
In the groupGeometry sop I am trying to figure out how to group only the odd numbered points with an expression and am not having much luck...
Thanks in advance for any help here.

A real simple way would be to use the scatter sop to scatter points along the surface and use that as the template geometry with a copy sop and a box that is scaled to suit.

Here is a very simple setup that does exactly what he said...pin constraint's tied to torus position. I have animated this opening and closing.
